ぎ材３，３ａで構成されることになる。 In FIGS. 1 to 3, both side frames 2 of a staircase 1 are constructed by assembling steel pipes into a truss shape, and both ends of the upper chord members 21 form bent portions 23 bent outward. The lower chord members 22 are connected by a horizontal connecting member 3 made of a steel pipe, and the upper side of this horizontal connecting member is connected by a vertical connecting member 3a made of round steel. Therefore, the bottom of the staircase 1 is made up of connecting members 3, 3a arranged in a grid pattern.
また側枠２間には踏板４を取り付けてある。こ
の踏板の底板４１は第５図に示すように両側に立
上り部４１１を形成した断面ほぼＬ字状の鉄板を

タル４２を充填してある。 Further, a footboard 4 is attached between the side frames 2. As shown in FIG. 5, the bottom plate 41 of this step board is made by combining iron plates having a substantially L-shaped cross section with rising portions 411 on both sides on the stairs, and is fixed to the vertical tie member 3a by welding. The top of the bottom plate 41 is filled with resin mortar 42.
また側枠２の上弦材２１に沿つてこれより上方
にスチールパイプからなる手摺５を配設してあ
る。この手摺は上弦材２１に連結材５で連結して
いる。手摺５の両端は上弦材２１の屈曲部２３に
沿つて屈曲した屈曲部５１となつており、両屈曲
部２３，５１とが階段の横座屈を防止している。 Further, a handrail 5 made of a steel pipe is provided along and above the upper chord member 21 of the side frame 2. This handrail is connected to the upper chord member 21 by a connecting member 5. Both ends of the handrail 5 are bent portions 51 bent along the bent portion 23 of the upper chord member 21, and both bent portions 23, 51 prevent horizontal buckling of the stairs.
手摺５と上弦材２１とが平行に位置しているこ
とによつても横座屈の防止が図られる。 Horizontal buckling can also be prevented by the handrail 5 and the upper chord member 21 being positioned parallel to each other.
手摺５も階段の構造体となり、階段の構成部材
を無駄なく利用している。 The handrail 5 also forms part of the structure of the staircase, and the constituent members of the staircase are utilized without waste.
階段１の取付け状態を説明すると、第１図に示
すように下部はフロアＦの２点Ａ，A1で支持し、
上部は上階のフロアF1に上階の梁Ｂとその下方

におけるモーメントは小さくなり、小さな部材で
も支持できる利点がある。もちろん、上下各１支
点で階段を支持してもよい。 To explain the installation state of the stairs 1, as shown in Fig. 1, the lower part is supported at two points A and A1 on the floor F.
The upper part is supported on the upper floor F1 by two points: the upper beam B and the supporting steel frame B1 below. In this way, when there are four fulcrums, the moments at various parts of the members of the staircase 1 are reduced, and there is an advantage that even small members can be supported. Of course, the stairs may be supported by one fulcrum each at the top and bottom.
